Octagonal Sapphire Collection

The octagonal mixed cut gives sapphires a distinctive eight-sided outline with a combination of step and brilliant faceting. It sits between the clean geometry of an emerald cut and the sparkle of a radiant, offering the best of both worlds. This shape is popular for larger sapphires because it retains weight well and shows color evenly across the stone. We source ours from partner mines worldwide. Direct, no middlemen. The octagonal outline gives a structured, architectural look that works especially well in bezel and channel settings. Color distribution matters most in this cut since the open facets let you see right into the stone. Browse our octagonal sapphires below.
